Abstract

The wheelchair has left and right rear rocker arm, with each arm having its end pointing forwards in the direction of travel (F). The arms are height-adjustably mounted in a horizontal axle (8) on the chassis' lengthwise strut (9). The back end is supported by the spring (6) linked to the rocker-arm and formed by a shock-absorber or pneumatic spring, with an affixed drive mechanism (3). A space (FR) between the two rocker-arms extends from the back of the wheel-chair to the rocker arms pivot axles (8). The rocker-arm is made of a single aluminium body reinforced by ridges, with container (12) for the drive mechanism. The rocker-arm spaced apart from the spring-bearing holders (13) has two superimposed bearing-holders (14) for an alternatively applied support-wheel (15). <IMAGE>

Description

Die Erfindung bezieht sich auf einen Rollstuhl für Behinderte und Kranke, bei dem die beiden Hinterräder mit je einem elektromotorischen auf der Radachse jedes Hinterrades sitzenden Antrieb verbunden sind und jedes Hinterrad gegenüber dem Rollstuhl-Fahrgestell durch ein zwischen Fahrgestell und Antrieb angelenktes Federorgan einzeln abgefedert ist.The invention relates to a wheelchair for the disabled and the sick, in which the two rear wheels are each connected to an electromotive drive located on the wheel axis of each rear wheel and each rear wheel is individually cushioned relative to the wheelchair chassis by a spring element articulated between the chassis and the drive.

Ein derartiger Rollstuhl ist aus der EP-PS 0 339 500 bekannt geworden.Such a wheelchair has become known from EP-PS 0 339 500.

Hierbei ragen die beiden auf jeweils einer Radachse sitzenden und verhältnismäßig großvolumig ausgebildeten Antriebe weit in den Raum zwischen den beiden Seitenteilen des Rollstuhles hinein und diese Antriebe sind noch zusätzlich durch querverlaufende Kugelgelenkstangen gegen Bewegungen gesichert, so daß der Zugangsraum von der Rückseite des Rollstuhles für das Einbringen der Batterie stark eingeengt ist und diese Batterie auch nicht, wie gewünscht, im Schwerpunkt des Rollstuhles zu liegen kommt.Here, the two relatively large-volume drives seated on each wheel axle protrude far into the space between the two side parts of the wheelchair and these drives are additionally secured against movement by transverse ball joint rods, so that the access space from the rear of the wheelchair for insertion the battery is severely constricted and this battery does not come to rest in the center of gravity of the wheelchair as desired.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, den Rollstuhl mit einer verbesserten Abfederungslagerung für jedes der beiden angetriebenen Hinterräder auszustatten und dabei zwischen den beiden Abfederungen einen gut zugänglichen Aufnahmeraum für eine im Schwerpunkt des Rollstuhles einzusetzende Batterie zu schaffen.Based on this prior art, it is an object of the invention to provide the wheelchair with an improved suspension mounting for each of the two driven rear wheels and to provide an easily accessible receiving space for a battery to be used in the center of gravity of the wheelchair between the two suspension systems.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.

Weiterhin ist es Aufgabe der Erfindung, die Hinterräder jeweils durch einen eine flache Bauweise zeigenden Antriebsmotor anzutreiben, durch den zwischen den Seiten des Rollstuhles ein großer Freiraum geschaffen werden kann.Furthermore, it is an object of the invention to drive the rear wheels in each case by means of a drive motor which shows a flat design and by means of which a large clearance can be created between the sides of the wheelchair.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 4 gelöst.This object is achieved by the characterizing features of claim 4.

Die übrigen Ansprüche beinhalten Gestaltungsmerkmale, welche vorteilhafte und förderliche Weiterbildungen der Aufgabenlösungen darstellen.The remaining claims contain design features which represent advantageous and beneficial further developments of the task solutions.

Bei dem Rollstuhl gemäß der Erfindung wird für die abgefederte Lagerung jedes Hinterrades eine schwenkbar an Fahrgestell-Seitenholmen angreifende Schwinge und ein Stoßdämpfer eingesetzt, wobei an der Schwinge gleichzeitig das Hinterrad und der Antriebsmotor gelagert sind, so daß jedes angetriebene Hinterrad für sich allein abgefedert am Fahrgestell gehalten ist.In the wheelchair according to the invention, a swinging arm and a shock absorber are used for the sprung mounting of each rear wheel, and a shock absorber is applied to the swing arm, the rear wheel and the drive motor being mounted on the swing arm at the same time, so that each driven rear wheel is independently cushioned on the chassis is held.

Durch diese separate Abfederung der angetriebenen Hinterräder gleichen diese unabhängig voneinander die Fahrbahnunebenheiten aus und bleiben dadurch stets mit der Fahrbahn in Kontakt, was einen gleichmäßigen Antrieb des Rollstuhles bewirkt und eine einwandfreie Lenkmöglichkeit ergibt. Hierdurch erhält die den Rollstuhl benutzende Person ein sicheres Fahrverhalten durch die Abfederung zwischen angetriebenen Rädern und Stuhlgestell eine optimale Sitzeigenschaft.Due to this separate cushioning of the driven rear wheels, these compensate for the unevenness of the road independently of one another and thus always remain in contact with the road, which results in a uniform drive of the wheelchair and results in a perfect steering possibility. This gives the person using the wheelchair safe driving behavior thanks to the cushioning between the driven wheels and the chair frame and optimum seating properties.

Die Schwinge ist für den Rechts- und Linkseinsatz identisch ausgebildet, so daß für den Rollstuhl nur ein Schwingentyp erforderlich ist.The swing arm is identical for right and left use, so that only one type of swing arm is required for the wheelchair.

Die Schwingen laufen dabei entgegen der Fahrtrichtung schräg nach hinten und unten und ihr Lagerpunkt an dem Fahrgestell ist verhältnismäßig weit nach vorn gelegt. Durch diese beiden Schwingen und den Einsatz des Stoßdämpfers entfallen die bisher üblichen querverlaufenden Kugelgelenkstangen und dadurch ist der Aufnahmeraum für die Batterie von der Rückseite des Rollstuhles gut zugänglich und die Batterie läßt sich verhältnismäßig weit nach vorn in diesen Aufnahmeraum einsetzen, so daß sie im Schwerpunkt des Rollstuhles zur Unterstützung der Fahrsicherheit desselben liegt.The rockers run obliquely back and down against the direction of travel and their bearing point on the chassis is relatively far forward. Through these two Swinging and the use of the shock absorber are no longer the usual transverse ball-and-socket rods, which means that the battery compartment can be easily accessed from the rear of the wheelchair and the battery can be inserted relatively far forward into this space so that it can be used to support the wheelchair the driving safety is the same.

Weiterhin wird dieser gut zugängliche Aufnahmeraum durch die Ausbildung des Antriebes als getriebeloser elektrischer Antriebsmotor in Flachbauweise unterstützt, der nahezu vollständig in die Felge des Hinterrades eingreift und somit zwischen beiden Schwingen nicht platzbeeinträchtigend hervortritt.Furthermore, this easily accessible receiving space is supported by the design of the drive as a gearless electric drive motor in a flat design, which engages almost completely in the rim of the rear wheel and thus does not protrude between the two wings.

Die Schwinge ist in kostengünstiger Weise als einstückiges Aluminiumteil herstellbar und zeigt am vorderen Ende eine abgewinkelte hülsenförmige Lageraufnahme für die Schwenkachse am Fahrgestell und am hinteren Ende mehrere Lageraufnahmen für den wechselweisen Einsatz und das Anbringen des Stoßdämpfers sowie eines Stützrades.The swing arm is inexpensive to manufacture as a one-piece aluminum part and shows at the front end an angled sleeve-shaped bearing holder for the swivel axis on the chassis and at the rear end several bearing holders for alternating use and attaching the shock absorber and a support wheel.
